DESCRIPTION
Input for voltage input. A 1µF or greater capacitor should be placed in
this pin.
Ground.
Enable pin. Pulling his pin low, can shut down the PMOS pass transistor,
and the current consuming can be set less than 1µA.
Output voltage pin. The capacitor which connected between this pin and
GND should be decoupled with a 2.2µF or a greater value low ESR
ceramic capacitor.
Remote Sense.
Ground.
Bypass capacitor for noise reduction.
Enable Input.
Supply Input.
Output Voltage.
